METHOD AND DEVICE FOR SURFACE PROCESSING OF FIRST WALL OF NUCLEAR FUSION REACTOR

摘要

PURPOSE: To collect tritiums effectively by furnishing an oxidated gas supplying means to supply oxidated gas to the first wall of a nuclear fusion reactor and also an oxidated gas regenerating means to feed the oxide gas in the exhaust gas to the mentioned oxidated gas supplying means. ;CONSTITUTION: An oxidated gas supplying means 20 to supply ozone gas to the armor 9 of the first wall 6 of a nuclear fusion reactor is equipped with an oxygen supply line 21 and ozonizer 22. These two parts 21 and 22 are connected together through a piping 23, and the outlet from the ozonizer 22 is connected to the armor 9 of the first wall 6 through a piping 24. The ozone gas supplied by the ozonizer 22 reacts with hydrocarbon compounds containing tritium attached to the armor 9, and exhaust gas is produced. This exhaust gas contains tritium water, products from oxidating reaction, and oxygen gas. An oxide gas regenerating means 30 is equipped with an exhaust pap 31 and an adsorptive tower system 32. The inlet to the pump 31 is connected with the armor 9 through a piping 33, while the outlet from the pump 31 is connected with the inlet to the adsorptive tower system 32 through a piping 34.;COPYRIGHT: (C)1995,JPO
